Hi I'm 32, male with Norwood 3 hair loss but I shave it short now because of the receding hair line, I think my hair is thinner on top but not sure as there is still a lot, I would like to know if I got a hair system what would happen to my hair underneath? Would it continue to grow and push the system off? go bad causing infection? Start to die more rapidly and fall out which wouldn't bother me to be fair as I would have a system over it, also how often do these systems need to be replaced as the least? The surgery would tell you every 4 weeks to get more money out of you but I can't afford that, I'm an electrician but have kids and a mortgage which is more important, ideally every 8 weeks would be more affordable or more if possible, thanks for your help
